Definitions

  • the invention relates to a switching arrangement, which is provided in particular for a DC operation, comprising at least one switching chamber, each switching chamber two switching pieces, each having a first contact region, a movable with a switching bridge and electrically conductive bridge switching piece with two second contact areas for producing an electrically conductive connection between the first and second contact areas and for separating at least one of the second contact areas of the respective first contact area, and at least two magnets for generating a magnetic field.
  • Electrical switches are components in a circuit that establish or disconnect an electrically conductive connection by means of internal, electrically conductive contacts. With a live connection to be cut, current flows through the contacts until they are separated. When an inductive circuit is disconnected by a switch, the current flow does not reduce immediately to zero, so that an arc can form between the contacts.
  • the arc is a gas discharge by a per se non-conductive medium, such as air.
  • AC alternating current
  • arcs usually erase at the zero crossing of the alternating current. Since such a zero crossing of the current in switches with DC operation (DC) is missing, stable arcing can occur when disconnecting the contacts.
  • the extinguishing chambers which serve to extinguish the arc, are intended to keep the period during which the arc burns as short as possible, since the arc releases a large amount of heat, which is used to burn off the contacts and / or the thermal load Switching chamber leads in the switch and thus reduces the life of the switch.
  • the space requirement for switches with corresponding extinguishing chambers, especially for non-polarity switch is significant. In two- or multi-pole switches correspondingly higher amounts of heat are released by arcs than in single-pole switches, which in turn requires larger switch housing with higher space requirements.
  • document DE 1 640 804 A1 explains an electrical switching device. In the contact system with bridge contact fixed contacts are formed with extending to both sides rails.
  • Plate-shaped permanent magnets are mounted parallel to the rails on the outer walls of an arc chamber, which generate a magnetic field perpendicular to the rails, which blows out the arc between the bridge and fixed contact forming up or down depending on the current direction.
  • An arrangement which allows a single-pole circuit can be formed as a bipolar switch arrangement by a further identically constructed arrangement which is set aside.
  • An object of the invention is to provide a switching arrangement with a fast and reliable erase behavior of resulting Ausschaltlichtbögen available, the space requirement of the amount of heat released is adjusted, without thereby increasing the variety of parts of the switch housing is increased.
  • each switching chamber has two contact pieces, each with a first contact region, and an electrically conductive bridge contact piece which can be moved with a switching bridge.
  • the bridge contact piece is an electrically conductive connection between the first and second contact areas produced, wherein a easy interrupting switch is separable only via one of the contact pairs of the first and second contact region, while the other contact pair remains permanently connected, for example via a strand.
  • the two second contact areas are separated from the respective first contact area.
  • each chamber has at least two magnets, in particular permanent magnets.
  • a modular construction of the switching arrangement wherein the switching arrangement is provided with only one switching chamber for a single-pole operation and can be extended by adding at least one second switching chamber for a multi-pole operation.
  • the space requirement of the switching arrangement of the resulting amount of heat can be adjusted by Ausschaltlichtbögen.
  • the modular construction advantageously allows uniform switching chamber components to be used to produce single or multi-pole switches.
  • a preferred embodiment relates to a two-pole operation of the switching arrangement, wherein two switching chambers are connected to each other such that their respective opening sides face each other. Also preferably, the switching chambers for a two-pole operation by a plate against each other are electrically isolated, the plate is used in a single-pole operation as a cover of the individual switching chamber housing. In a two-pole operation, the two switching chambers preferably have a common switching bridge for moving the bridge switching pieces. According to a preferred embodiment, it is provided that an additional magnet for influencing the magnetic field is arranged on the movable switching bridge for each switching chamber.
  • an advantage of this additional magnet is that the magnetic field in the region of the first and second contact regions is particularly well influenced, since the additional magnet passes through the movement of the switching bridge in the immediate vicinity of the first and second contact areas.
  • the field strength of the magnetic field in this area is significantly increased by the additional magnet, which advantageously accelerates quenching of Arc allowed.
  • the additional magnet is preferably arranged in a recess in the movable switching bridge in height of the contact areas.
  • the magnetic field is used to exert a magnetic force on the arc or arcs, so that at least one of the arcs, preferably independently of the current direction in the arc, is driven in the direction of one of the extinguishing devices, wherein the contact pieces of the switching chambers are arranged so that the second contact areas are located in a line substantially perpendicular to the direction of movement of the arcs.
  • the additional magnet is movable to amplify the magnetic field strength with the switching bridge in a region of the separable first and second contact areas.
  • the auxiliary magnet is movable in close proximity to the region of the first and second contact regions, not between the first and second contact regions.
  • the at least two magnets are, for example, at least twice as far away from the first and second contact regions as the additional magnet.
  • the at least two magnets can in particular be arranged outside the switching chamber or in the region of the switching chamber wall, also on the inside of the switching chamber wall, preferably in an insulating pocket.
  • the magnets are preferably designed as at least two plate-shaped magnets whose surfaces are arranged parallel to each other.

  • the switch is designed in the form of two overlapping switch chambers 41a, 41b of preferably identical construction, which makes this possible in particular to realize a single-pole switch with only one switching chamber 41b or this modular, by adding a further switching chamber 41 a, to develop a two-pole switch.

  • the first and second contact areas 11, 31 and 21, 31 are also referred to below as fixed contact areas 11, 21 and movable contact areas 31, which form contact pairs.

  • the movable contact areas 31 are located in each case at the intersection between the bridge switching piece 30, which are rotated by approximately 90 degrees against the connecting axis of two opposing extinguishing devices 61, 62, and from there perpendicularly outgoing arc running plates 32nd
  • FIGS. 3a and 3b are two perspective views of the switching arrangement according to FIG. 1 , but without chamber walls of the switching chambers 41a, 41b, shown.
  • the perspective in FIG. 3a corresponds to the FIG. 1 while the FIG. 3b a 90 degree rotated perspective shows.
